Title: Improve String() performance

Before:
```
BenchmarkStringSimple 5000000 305 ns/op 16 B/op 1 allocs/op
BenchmarkStringComplex 1000000 1361 ns/op 569 B/op 5 allocs/op
BenchmarkStringAverage 2000000 906 ns/op 290 B/op 3 allocs/op
```

After:
```
BenchmarkStringSimple 10000000 197 ns/op 16 B/op 1 allocs/op
BenchmarkStringComplex 5000000 511 ns/op 88 B/op 3 allocs/op
BenchmarkStringAverage 5000000 412 ns/op 56 B/op 2 allocs/op
```

At this point, none of the delimiter constants (`dot`, `hyphen`, `plus`) are being used. We can remove them or make an effort to use them everywhere. I have a commit for the latter already, but what do you prefer?
